Shuichiro Kudo is a man who has everything he wants from life: a job as successful doctor and his own home. However one evening he finds a tiny angel trapped on a branch and frees him. The angel, named Kohaku, offers Shuichiro a wish in return for saving him, but Shuichiro wants nothing. Kohaku however, is determined that there has to be a wish Shuichiro cannot grant by himself and follows him home. Kohaku reveals that he has left heaven to locate another angel, Hisui who has abandoned heaven, but a devil and his two catty servants constantly hinder Kohaku's search! Will Kohaku find Hisui and will Shuichiro realize that some wishes can only be granted by others?
Both are stories about angels and demons on earth, involving complicated romances between various species. Reading one is strongly reminicient of reading the other, and people who enjoyed one will no doubt enjoy the other
In addition to both being penned by the manga group CLAMP, both Kobato. and Wish share similar themes of eternal love, loss, sacrifice and soulmates. Both Kobato and Kohaku are loveable goofballs, who also have pure hearts and the gift of song.
It's also worth mentioning that in true CLAMP fashion, the world both stories take place in are the same. As such, the plotlines of both of these manga are related and I feel that Kobato is basically something of a sequel to Wish, as Kohaku and Shuichiro do make an important appearance in Kobato. So, basically, if you wanted more of Wish, read Kobato - and if you like Kobato and want to see CLAMP's earlier attempt at a very similar storyline, read Wish.
Demon's and angels have a way with falling in love with humans or one another. Both Wish and BlackxBlack are touching stories about 2 people falling in love from very different ways of life. If you liked one check out the other.
